应用断层切皮法判断脱套伤撕脱皮肤的活性

对大面积皮肤撕脱伤，撕脱的皮肤往往部分成活，应避免将其全部切除。清创后，将撕脱的皮肤暂时原位缝合，并对其作断层切片，真皮有渗血的部分则表示皮肤仍成活。沿渗血与非渗血的界限将无渗血的皮肤切除，可以最大限度地保留有活性的皮蒂。１９９１年７月￣１９９３年５月，应用本方法治疗８例病人，撕脱面积最小６％，最大１３％。经治疗后，９０％皮肤成活，功能及外形均较满意。

ABRTRACTJUDGEMENT OF SKIN VIABILITY IN DEGLOVING INJURIES BY SPLIT-THICKNESSSKIN EXCISION

n extensive friction-avulsion injuries,part of the injuried sk in was stifl viable, so that totalexcision of the avulsed sk in should be avoided, After debridememt,sutured the avulsed skin flapin sit u temporarily and took a split-thick ness graft from it. If bleeding occurred from the s plittedsurface of the dermis which was meant that part of the sk in was alive, Along the border betweenthe bleeding and non- bleeding area,the non-bleeding area of sk in was excised.This could pre-serve the viable skin to the maximal extent.From July 1991 to May 1992.the viability of theskin in 8 avulsion injuries was judged.The maximal avulsed area was 13%and the minimal was6%of the total body surface. After the treatment,90%of the avulsed skin was alive. The ap-pearan ce was satisfactory .
